Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a network system implements real-time monitoring and control of energy usage, storage, and distribution, then energy management efficiency is improved, but system complexity increases

Engineering Contradiction:
Improveenergy management efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The network system is divided into distinct functional components including utility area network (UAN) for energy production and distribution, home area network (HAN) for consumption and storage, and advanced metering infrastructure (AMI) for communication. This segmentation allows each component to be optimized independently while maintaining overall system efficiency, resolving the contradiction between management efficiency and system complexity.

Inventive Principle:
Principle #1Segmentation

2Productivity

If the system integrates multiple communication networks (utility and home area networks), then energy distribution optimization is improved, but communication infrastructure complexity increases

Engineering Contradiction:
Improveenergy distribution optimizationVSAvoidcommunication infrastructure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The advanced metering infrastructure (AMI) serves as an intermediary communication layer that bridges the utility area network and home area network. The AMI includes smart meters, communication modules, and data processing units that facilitate standardized information exchange between UAN and HAN, reducing the complexity of direct multi-network integration while maintaining optimization capabilities.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Loss of information

If the system provides comprehensive real-time monitoring of energy production, distribution, and consumption, then energy visibility is improved, but data processing requirements increase

Engineering Contradiction:
Improveenergy visibilityVSAvoiddata processing requirements
Core Design Contradiction:
Loss of informationVSQuantity of substance

Solution Approach 1:

The system implements feedback mechanisms where smart meters continuously monitor energy parameters and transmit data through the AMI to both utility and home energy management systems. This feedback loop enables real-time visibility of energy production, distribution, and consumption while using standardized communication protocols to minimize data processing overhead. The feedback structure allows for localized decision-making at both utility and consumer ends, reducing the need for centralized processing of all raw data.

Inventive Principle:
Principle #23Feedback

AI summary

Provided is a network system. The network system includes a first component performing a preset function, the first component having a first device code and a second component exchanging information with the first component to be communicably connected to the first component, the second component having a second device code. When a command for communicable connection is inputted into the first component or the second component, a connection sequence is generated from the component in which the command is inputted to exchange an IP address and the device code of each of the components between one component generating the connection sequence and the other component receiving the connection sequence.
